CASH-REGISTER.

To all whom it may concern:

Be it known that I, EDMUND S. CHURCH, a citizen of theUnite'd: States, residing at Dayton, in the .county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Cash-Registers, of which I declare the following to be afull,

' clear, and exact description.

The invention relates to cash registers, and has among its objects to provide an improved machine of this typeadapted to receive a number of kindsof entries.

The machine produced is whatmay be termed a duplex cashregister; that is, one consisting of a plurality of registering devices, andan equal number of sets of controlling devices therefor, with a common operating device. a

The invention also comprisesmeans for preventing the use of more than one de;

partment ofthe duplex machine at the same operation.

As a matter of further improvement,

means are provided for requiring-thedepressionofan initial or transaction key, as well as amount keys, at eachoperation, and in the present embodiment this result is produced by a machine lock which requires the use of the said; two varieties of keys to release the. lock... v a y U The usual shutter or flash is provided, but there has been added to its usual concealing function a second function, to wit, that of a. clerks or transaction-indicator.

With these and incidental objects in view, the invention consists in certain novel features of construction and combinations of parts, the essential elements ofwhich are set forth in appended claims and a preferred form of embodiment of which is hereinafter [specifically described with reference to the drawings'which accompany and form part of this specification. 7 v

United States, issued to J P. Cleal and F. A.

Reinhard, No.-580,378, April. 13, 1897. This patent describes a machine of the so-called two-motion typeg that is, one in which. keys or their; equivalent serve to determine the v differential motion. ofthe actuating devices for the register proper, the powerbeingfur 1 nishedbya crank-handle. This mechanism -Means are provided, for

preventing the; use of the twjo departments at the same operation The machine is inh tended in general .gto be used by-t' -VO separate clerks, or for two separate departments. In

such case, each clerk] or each department would be assigned one of the part-s of the duplex machine. The operation of anykey in either department serves immediately to lock the keys of theiother department from j operation. The machine is normally locked, and in order to unlock the sam'e,1t is necessary t-o press not only an amount key, but

also clerks or transaction key, the 00111- bined peration of the two. serving to 11H". lock the machine. As an indication (of.

which elerks key has be'en operated', a clerks I the said keys, and inasmuch asonly one clerk will use the machine ,at any one time} the clerks indieators'are also used place of the usual shutter or flash. V Describedin general terms, the machine comprises a frame '10, (see Fig. 2), carrying" a main rod 11, on whichfare' journaled a plu-" ralityv of segments '12. These "segments carry rack-teeth-13,.meshing with a gear 14,

on the shaft 14f which also meshes with "a second gear 15, rigi'd'with ani'ndicator 16. A; bank of keys 1'? is provided for each segment 12, andthese keys when depressedare adapted to liinit tlie'motion of the segment.

The motion is primarily caused by a seg ment 18, also journaled on therod 11, and

connected to which is a crank 19. This crank, through a link .20 and a second" crank 21, is moved by the rotation of main shaft 22, which is given a complete rotation at each operation of the-machine. It will be understood that there is a plurality of banks'of keys, and an equalnumber of seg ments'12'and cooperating parts in the ma-' chine. 7 I I To provide for the interlocking of the v two halves of the duplex machine, the mech anism shown in Figs. 3 and 4 isv provided. A rod 22 has rigid therewith-a plurality of detents 23. Those for the right-hand half of the-machine have hooks 24 projecting the oscillation of the segmental-detents 25' used in this type of machine. The keys 17 are provided with bevels 26 (see Fig. 3) adapted to abut beveled slots 27 in the detents 25 and raise the said detents when the keys are depressed. It willbe evident from the structure of the detents 23 that when the detents 25 are raised, pins 28 carried thereby will rock the detents 23 by means of the beveled parts 29 of the hooks 24. Supposing-the detent 23 to be rocked forwardly, as shown in igs. 2 and 3, it is evident that this forward rocking will carry the straight portion 30 of the detent 23, shown in Figs. 4 and 5, directly over the pin 28 on the segmental detent 25. This evidently provides for lockingthe keys, as above stated, inasmuch as a depression of the key necessitates a raising of the detent25, corresponding to the particular bank, but such raising is prevented by the forward movement of the detent 23. It will therefore be evident thatthe first of the abovementioned objects is provided for by this structure. When any key of the right-hand half of the machine is operated, the detents 23 are moved forwardly, and the left-hand,

half of the machine is thereby locked out of operation, but the remaining banks in the right-hand half may still be used.

To compel a depression of an amount key and a transaction or clerks key at each operation, the mechanism shown in Figs. 4 and.

5 has been provided. As abovestated, the segmental detent 25 corresponding to a given bank of keys is raised when any key in that bank'is depressed. The detents for the amount banks have each a pin 37 near the upper part thereof, adapted to abut and move a curved lever 38, rigidly carried by a sleeve 39, loose on a shaft 39 On this sleeve is alsoa lever 40, having a curved projection 41, about which is coiled a spring 42.

The outer end of the curved projection 41 is.

pierced by a pin 43, against which bears a flan e 44 on alever 45 tight on the said shaft 39. As shown in Fig. 6,.there is a' pin and slot connection between sleeve,39 and sha-ft'39. Alever 451 is rigidly mounted" on and. extends rearwardly from the shaft 39f, and'at the extreme end thereof has a projection 47 ada When an amount key is depressed, pin 37 on the detent 25, Fig. 5, will then rock lever 38,

in order to show the ted to engage a notch '48 in a disk 49, rigid with the shaft 221.

" thereby rocking sleeve 39 and lever 40.

Thismovement of lever 40 ,wi'l tension spring 42, inasmuch as the lever 45 has a projection 46 abutting a pin 471 on the segmental detent- 25 corresponding to the clerks keys. W'hen a key" in the clerks bank is operated, the lug or pin 47lwill be raised into line with the notch 49 on the lever 45, and the tension of sprin 42 will then rock levers 45 and 451, thereby withdrawing the projection 47 from the notch 148 of the disk 491, and unlocking the machine. It will be evident that with this structure the amount key may be depressed before the clerks key, or the reverse may occur, or they may both be depressed together. In the first case the lever 38 would be first rocked, and the operation will be as was previously stated. If the clerks key is pressed first, the lug 47 will be moved in line withthe notch 49, but lever 45 will not move, as spring 42 isnot then under tension. hen the amount key is then depressed, the spring 42 will cause'an operation' of lever 45, andunlock the machine;

It will be evident that if .both keys are depressed at once, the same ultimate result will be produced.

lVith the particular style of duplex machine herein shown, the above described control for the main operating mechanism can be applied to one section only of the ma chine for the obvious reason that if both sections were equipped with this style 01 control the detent cohperating' with the clerkskeys of the unoperated section would prevent the rocking of shaft 39 by the lug 471 of said detent engaging with the projection 46 of its companion arm 45. For this reason the above described control is shown in connect-ion with the left hand end'or clerks A section only, the clerks detent of the other section unlocking the main operating mechanism by rocking the shaft 31') in a manner similar to that shown in the aforementioned Gleal and Reinhard patent.

It is usual in this type of machine to provide what is termed in the-art a flash, or shutter, to compel a complete operation of the machine. If the machine is only partially operated, the flash will remain in concealing position and prevent an observer from seeing the indicators. It is also somewhat usual to provide an operator or clerks indicator in addition to the value'indicators, person operating the machine. -Mechanism is provided whereby both these functions are single structure, his mechanism being shown in Figs. 1, 2 and 7.

It is evident that only one of the clerks indicators will be used at anyone operation, but it is a-lso necessar that both of the indicators (with regar to their concealing function) should bemoved concealing p0 \130 H performed with a 5 the machine, and at the end of. the operation of the flashes, depending on the clerks key depressed, is withdrawn.

on reference to Figs. 2 and 7 it will be seen that flashes 51 are provided one for one or the other eachof the duplicate sets of indicators, these flashes being carried by frames 52 journaled on the indicator supportlng shaft Connected to each flash by pins545 are links 55 having slots 06 straddling the operating 5 shaft 22 and near the bottom of each link as shown, and having influence of spring a of the machine.

is an antifriction roller 57 adapted to move in cam slots 58 in one oftwo disks 59 rigidly mounted on said shaft 22, the cam slots 58 extending only part way around thedisks the eXit parts thereof normally covered by spring pressed pawls 60. The springs 61 and 62 are provided one being connected to each of the'two links 55 at the top of the spring and at the bottom thereof being connected to one of the two arms 63 mounted on a rod 6 1 and. forming therewith a two'armed lever. arms has projecting therefrom a pin 65 adaptcd to ride in a notch 66 of a lever 67 which is journaledon a. pin (38. Connected to the lever 67 is a link (39, which is attached at its forward end to the retaining bar used in this type of machine. This retaining bar' is normally held in its forward position against the tension of spring 71' by the segmental detent 25, previously referred to. When the detent is raised, the retaining bar can then spring rearwardly under the 71. Although there are two links 55 connected to the two flashes, there is only one link (59 and lever 67 and this link 69 is connected to the retaining bar 70 for the extreme right-hand bank of keys The mechanism is 'in effect normally set to work on the A side. When the machine is operated, rotation of the disks 59 will cause the ant-ifriction rollers 57 to move through the exits of the slots 58. After .the first operation of the machine only one of the pins wouldbe in its slot at any giventimebut no matter which pin was in the slot it will be forced by the cam portion thereof downwardly immediately after the starting of the machine. The other flash corresponding to the clerks key which had been used at the previous operation will remain in concealing position. The "antifriction rollers 5'7 will ride on the pcriphery of the disks 59 until the forward or entrance end of the cam slots 58 reach them. It will be remembered that the retaining bar 7 0 "controls the tensioning of the-springstil and 62. In the position shown spring 61 1s tensioned while if the clerks key had been operated and the retaining bar moved rear- One of the ward its spring 71 would overpower the spring 62 and tension it atthe same time releasing the tension of spring 61. in the p0 sition of the figure spring 61 will hold down the link; 55 to which it is connected, thereby preventingthe antifriction roller 57 thereon from rising into the entrance of the slot 58 corresponding thereto, but as spring 62 is not tensioned the other link 55 will rise under the energy of its spring 62* causing its antifriction roller 57 to enter the cam; slot 58 and thereby permitting a return of the corresponding shutter 51' to the exhibiting position as in Fig- 2. This mechanism evidently provides for the result above iii-- dicated-that is, that both of the flashes shall be brought to concealing position at the beginning of each operation, this being a resultant of the exit of the slot 58, which depresses both of the'links 55. When the operation is partly finished, one of the fric- I,

tion rollers 57,will be allowed to move into the slot- 58 at the. entrance part thereof,

whereas the other friction roller will be comell ed to'r'emain depressed under tension of its spring 61 or ($2, and will thereby remain depressed at the'end of the operation. The clerks key indicated by B l in Fig. 1 controls the tensioning or loosening of springs 61. and 62, a11'd thereby determines which flash shall remain in concealing position. It will be of course understood that if the 1B clerks key is depressed, the result will be to withdraw the flash marked Clerk A andjlea ve in sight the flash marked Clerk B, and the reverse'will be true if the A. clerks key is depressed. 1 V

' It may sometimes be'desired by one of the clerks operating the machine to be able to lock his half thereof, as,for example, he leaves the establislu'nent for a short period. To accomplish this result, two locks .77 and 78, shown in Fig. 1, are adapted to control the movement of the detents 2S. lVhen a key is inserted. in one or the other of the 79 will move the-detents forwardly or rearwardly, depending on which of the two locks is operated, and. thereby 'prevent an operation of the keys in one or the other half of the machine."

\Vhile the form of mechanism here shown and described is admirably adapted-to fultil. the objects primarilystated, understood that it is not intended to confine the invention to the one form of embodilooks, and the bolt shot, the connecting bar H it is to be mcnt herein disclosed, for it is susceptible of embodiment in various forms all coming wit-hinthe scope of the claims which follow.
